WALL-PLUG.

Specification of Lettera Patent.

Patented Dec. 1, 1908.

Appllctlon led February 9, 1907, Serial No. 356,690.

To all whom it may concern:

Be it known that I, WILLIAM M. Hoi-inne, n citizen of the United States, residing ut Allegheny city, in the county of Allegheny und Stute of Pennsylvania, have invented certain new und useful In'iprovel'ueuts in Wall-Plugs; und I do dechire the following; to be a full, clear, und exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the saine, reference being had to the accom unying drawings, and to the figures of re Aercnce marked thereon, which form a part of this specification.

'Ihe object of this invention is to rovide a chen compact and durable wa I plu that wi l securely hold the material desire to fasten against the wall und that can be readily applied where desired.

y invention relates to improvements in plugs for walls Where heretofore blocks of wood und other plu s were used.

Itis designed to e placed between bricks either when erecting, or afterdhe walls are built, by removing material to make room between the bricks or making an opening in sog cement walls [urge4 enough to receive the plu then when fastening the material to sai walls the nail is driven between und through making a positive hold,

It consists of u piece of lnetulperforoted or notched and formed or corrugated, euch side of seid holes or notches, and then bent close together forming u clump with extended lips at the open end us shown und hereafter more fully described. To enable others skilled in the nrt. to which my invention in'ipertnins to construct und use the saine, I will now describe it more fully, reference being hud to the accomplinying' draining forming por( ol this specification, in which Figure l is u pers motive. view showing the wall plugr sensed between tho bricks in u wull ,ready for use. Fig. lis o vertical view showing the wall plugI in pince with the. instel-inl nuilod to the wnll hy nie-uns ot' u nuil passing.r through suid nniteriul und extending through the closed notches of lhe plug Fig. 3W-

u sertionul rien' of the plug,r showin;r ihr unil driven-in pince, und the uniunvr el l'iolding-t`he nuil both, by nienns of the rorrogutions und the sharp edges oi' Closell notrhef.

In Fig. 2 the plug is shown us used by.

driving u unil through the material Suid nail passing between vthe corrngutions und out through the notched portion thereby not only having the benefit of the ressure of the corrugutions, but also the sinrp edges of the notches.

Where it becomes necessary to have the material to he fastened to the wall in u true line, and the surface ot wnll is irregular or not in u true line, two or more of these plugs cnn be pluced one in the other, or what is known ns telescopios' together until the desired trueI line is acquired. This feature of lelesropingr is also of considerable advantage in fillingr lui-ge or irregular openings as in the ordinary rough stone wull, und to readily contorni the flanges oi the plug to n straight liiul in such wulls.

In Fig. 3 the effect of the nuil or other de.- vice for fus-toning is shown. The suid device forces the col'rugutions outwurdly ugninst the woll, or substancebetween which the plug is plan-rd, und also pus-ses through the notched end, the` shnrp edges o'l which impinge un'ninsi the side of nul looking n secure hold. This fonture is very essential in the use oi devices of this kind.

In addition to the advantages heretofore enumerated niy improved plug hns the furv ther ndvnnlugr of being very cheap und eennoluirnl to manufacture, us hy reason of the nuiicrinl being of one piece, und eut without u'nsle of uiuteriul. Another udvuntngc is that this plug eun be unido in nny length which is of great udvnntuge for cement or brick Iloors or ns joisls vFor [mrtitions to hohl lnihingg or wuinscoting.

l rhiirn :is now und desire to secure by Letters Intenl l. woll plug consisting of n single piece of corrugated uuderiulforming :t seriosof ridges und depressions und h-nving n. rentrnl irons-verse line of perforulions pnrullel to seid-ridges. the .sold stri@ or picco being folded together on :i line through the perforations, thereby formin a clamp havin its ridges and depressions a ternating witht ose on the opposite side and forming an irregular restricted space between the walls of the clamp. g

2. A wall plug consistin of a singlepiecc of corrugated material avin a central transverse line of perforations, t e said iece being folded together on a line throug the perforations, thereby forming a clarlnp with gripng edges at folded per orations as descri ed.

3. A wall plug as described consisting of a single piece of stamped material .folde together, and having its foldedsedge notched out, thereb forming a clamp with gripping edges. at fo ded edge through notchin s.

4. A wall plug consisting of a. sing e piece of material corrugated so as to .form a series of ridges and depressions, its ends bent or flared outwardly and then folded together, and folded edge notched to form a grip as described.
